The Miyazaki Prefectural Government had slaughtered 42,000 chickens on a farm in the city of Miyazaki by Monday morning after a genetic test of dead fowl confirmed the presence of a highly pathogenic bird flu virus.

Chickens at the poultry farm in the Uranomyo area in the city tested positive for the H5 strain of the bird flu, the prefectural government said Sunday

The prefecture set up 10 sterilization points on roads around the affected farm.
